Description

Die Anmeldung betrifft ein wasserverdünnbares Konzentrat, ein wäßriges Mittel und ein Verfahren zur Behandlung von Holz gemäß dem Oberbegriff von Patentanspruch 1 bzw. 2.The application relates to a water-dilutable concentrate, an aqueous agent and a method for treating wood according to the preamble of claims 1 and 2 respectively.

Unter Holz werden alle Arten von Holz und Holzwerkstoffen, welche eine offenporige, den Applikationsmethoden der Imprägniertechnik zugängliche Struktur aufweisen, verstanden. Holzwerkstoffe sind beispielsweise Sperrholz, Tischlerplatten und Spanplatten.Wood is understood to mean all types of wood and wood-based materials which have an open-pore structure which is accessible to the application methods of impregnation technology. Wood materials are, for example, plywood, blockboard and chipboard.

Unter Holzschutzwirkstoffen werden holzschützende, biozide, die Lufttrocknung nicht inhibierende Wirkstoffe, und zwar in erster Linie solche mit insektizider und/oder fungizider Wirkung, verstanden.Wood preservation agents are understood to mean wood-protecting, biocidal agents which do not inhibit air drying, namely primarily those with an insecticidal and / or fungicidal action.

Die Anmeldung führt hin zur Imprägniertechnik von Holz und verwandten Techniken. Dabei wird ein wirksamer und dauerhafter Holzschutz angestrebt. In diesem Zusammenhang wird es als wichtig angesehen, das Bindemittel oder das Bindemittel und den Holzschutzwirkstoff in ausreichender Konzentration in die zu schützenden Holzteile zu transportieren (Penetration) und dort zu fixieren. Dabei kann unter Umständen zusätzlich eine dekorative Funktion in der Oberfläche des Holzes erzielt werden.Registration leads to the impregnation technique of wood and related techniques. Effective and permanent wood protection is sought. In this context, it is considered important to transport the binder or the binder and the wood preservative in sufficient concentration into the wooden parts to be protected (penetration) and to fix them there. Under certain circumstances, a decorative function can also be achieved in the surface of the wood.

Die Anmeldung führt nicht hin zur Lackiertechnik von Holz. Dort wird eine dekorative Funktion in der Holzoberfläche, jedenfalls keine Tiefenwirkung, angestrebt (Uberzugsmittel zur Oberflächenbeschichtung von Holz).The registration does not lead to the painting technology of wood. There a decorative function in the wood surface is sought, in any case no depth effect (coating agent for the surface coating of wood).

Auf dem Gebiet der Anmeldung sind bereits die DE-PS 28 38 930 und die DE-OSS 30 26 300 und 32 00 782 bekannt. (Auf dem Gebiet der Anmeldung gibt es noch die DE-Patentanmeldung mit dem Aktenzeichen P 32 14 196.) Das mit den dort beschriebenen übliche Trockenstoffe (Sikkative) enthaltenden Mitteln behandelte Holz weist bei der Lufttrocknung ein Trocknungsverhalten auf, das den Anforderungen der Praxis nicht immer genügt. Die Trocknung ist in der Regel erst nach 24 h ausreichend fortgeschritten, um imprägniertes Holz der Witterung ausgesetzt im Freien lagern zu können, ohne mit dem Auswaschen von Bindemittel oder Bindemittel und Holzschutzwirkstoff rechnen zu müssen.DE-PS 28 38 930 and DE-OSS 30 26 300 and 32 00 782 are already known in the field of application. (In the field of the application there is still the DE patent application with the file number P 32 14 196.) The wood treated with the agents described therein containing the usual dry substances (siccatives) has a drying behavior in air drying which does not meet the requirements of practice is always enough. Drying has generally only progressed sufficiently after 24 hours in order to be able to store impregnated wood exposed to the weather outdoors without having to reckon with the washing out of binders or binders and wood preservatives.

Die Aufgabe bestand darin, diesen Mangel zu überwinden und ein wasserverdünnbares Konzentrat, ein wäßriges Mittel und ein Verfahren zur Behandlung von Holz bereitzustellen, die es dem Fachmann ermöglichen, die Trocknungszeit bei der Lufttrocknung wesentlich zu verkürzen.The object was to overcome this deficiency and to provide a water-dilutable concentrate, an aqueous agent and a process for treating wood, which enable the person skilled in the art to significantly shorten the drying time in air drying.

Die Aufgabe wurde überraschenderweise wie in den Patentansprüchen angegeben gelöst.The object was surprisingly achieved as stated in the claims.

The type and quantity always depend on the material to be treated, its intended use and the treatment method, and can be easily determined with just a few orientation tests.

Da die in den erfindungsgemäßen Behandlungsmitteln eingesetzten Bindemittel lufttrocknend sind, ist es im allgemeinen nicht erforderlich, ihnen weitere Harze als Vernetzungsmittel zuzusetzen. Selbstverständlich können weitere Bindemittel, welche - gegebenenfalls bei Wärmebehandlung - als Vernetzungsmittel wirken, wie beispielsweise wasserlösliche Aminoplaste oder Phenolharze, mitverwendet werden, sofern der im Sinne der Aufgabenstellung der vorliegenden Erfindung angestrebte Effekt nicht wesentlich beeinträchtigt wird.Since the binders used in the treatment agents according to the invention are air-drying, it is generally not necessary to add further resins as crosslinking agents. Of course, other binders which act as crosslinking agents, if appropriate in the case of heat treatment, such as, for example, water-soluble aminoplasts or phenolic resins, can also be used, provided that the effect sought in the sense of the object of the present invention is not significantly impaired.

Die erfindungsgemäßen Behandlungsmittel haben im allgemeinen einen Bindemittelgehalt von 1 bis 40, vorzugsweise 5 bis 30 Massen-% und können nach allen bekannten Verfahren des Standes der Technik (vgl. DIN 68 800, Blatt 3) appliziert werden. Dabei ist die erzielbare Schutzwirkung - wie dem Fachmann bekannt ist - eng mit dem Behandlungsverfahren verknüpft. Besonders wirksam ist ein Imprägnierverfahren, bei dem das Holz, gegebenenfalls unter Druck oder Vakuum, einer Volltränkung unterworfen wird.The treatment agents according to the invention generally have a binder content of 1 to 40, preferably 5 to 30% by mass and can be applied by all known methods of the prior art (cf. DIN 68 800, sheet 3). The protective effect that can be achieved - as is known to the person skilled in the art - is closely linked to the treatment method. An impregnation process is particularly effective, in which the wood is subjected to full impregnation, possibly under pressure or vacuum.
